Re: can't change permissions on usb drive

As you suggested I formatted the drive Fat32 and it works. I had tried several drives before posting the first time, and I thought one was formatted as FAT (I just checked again, it wasn't). Your post brought me back to my senses. I followed your suggestion to install ntfs-3g as well. Thank you for ...

everything on the Pixel desktop is huge

I used NOOBS to install Rasbian, which brings up the Pixel desktop when booted. The default resolution for my 17" SyncMaster 711T is 640x480 pixels and the terminal window looks OK with that resolution. But in Pixel, everything looks huge - the icons, menu bar, text, windows and the contents of ever...

can't change permissions on usb drive

Could someone please advise a newbie on how to copy files onto a USB thumb drive? When I inserted a USB drive into the RasPi 3 it created a directory in /media/pi/ named E6025FD9025FACF5. When I try to copy files to the directory I get a permission error (since it has permissions r - x - - - - - -)....

Re: General Questions - BCM parts availability

My friends and I don't give up that easily. We have started tracing the PI3,2 and we will eventually finish. I was just asking if anyone out there had already done what we are doing to avoid duplicating efforts. So if no one has posted schematics and assembly drawings by the time we finish, we will....

Re: General Questions - BCM parts availability

Schematics are here: https://www.raspberrypi.org/documentation/hardware/raspberrypi/schematics/ no sure how much use they are since you can't buy the major parts. Unfortunately that is just a 1 page "reduced schematic" with no assembly drawing, and I inevitably need to know about something not on i...

Re: How can I use Xbee with Rasperry

You could also use a usb to XBee adapter . The only difference will be that the driver will be /dev/ttyUSB0 or /dev/ttyACMA0 Daniel, I'm too new at the RasPi to understand how to use these drivers. Please provide more detail if you can. Specifically, how do you set up the RasPi to pass commands and...

Re: how to spec library path?

Ok, I gotta admit I am dumbfounded that there were six posts before mine and nobody mentioned __init__.py. Is google broken? ... Nobody knows how to create and import modules? Yikes ....

Re: how to spec library path?

Thank you paddyg. I really appreciate the advice, and my python scripts are up and running, finally. This method works well, although I was hoping to avoid hard coding the path in my source file. A note to others using this method: Many paths can be added just by repeating sys.path.insert(1,'/home/p...

how to spec library path?

I am using the most current version of Rasbian, and I'm new to this so pardon my question: I have a directory /home/pi/mypython that contains a sub-directory /mylibrary and a python script. The script has a statement like "from LIBRARY_FILE import THIS_CLASS". LIBRARY_FILE is in the sub-directory /m...

Thank you.
The time/date was not setting properly, but it was due to a seemingly unrelated problem, now fixed. Thanks again.

Re: The Correct way to add a RTC

Great help, itsmedoofer, but some clarification, please.
You wrote "load up the RTC module and test by running, i2c-0 for and old Pi:-"
Specifically how do you modify the command "sudo modprobe rtc-ds1307" if using an old Pi?

set date,time with internet time server

How can I set up my Pi to always show the correct time/date after being powered off? Is there a way to use an internet time server for this?
